        Andrew Frank, <em>Int. J. of Geographic Information Systems</em></a>
         <b>10</b>(2), March 1996, pages 242-243. <P>

<em>This book may become a very important book for Geographic Systems
and for geography in general, despite the fact, that it does not
discuss anything geographical or spatial in its 400 pages.  ...  It
must be hoped that many geographers use the methods to model
geographical processes and to explore the dynamic behavior of systems
in physical and human geography.  Many M.Sc. or Ph.D. thesis could
benefit from the rigor of the method and the application of the
software.  Modeling of dynamic systems - a la Forrester's Urban
Dynamics - become feasible, even in the absence of detailed
quantitative knowledge. </em><p>
